The E12-200S is a fine example of a high quality transducer providing the right balance between performance and engineering costs. The E12-200S is a 400W program low frequency driver designed to satisfy the need for a 12″ loudspeaker which combines excellent linearity with good sensitivity and power handling characteristics. It is primarily intended for compact bass reflex applications in enclosures as small as 40 lt, typically for two-way systems in combination with 1” compression driver. The high quality paper cone has a smooth, curvilinear profile design that eliminates bell-mode resonances within the intended frequency range. This is carried by a specially treated, dampened double half-roll linen suspension which has been designed to control excursion maintaining the piston action linearity. Voice coil cooling is achieved by incorporating airways between the chassis back plate and the top plate of the magnet, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. This technology is another result of the 3D CAD resource application by our engineers.
